OA62088: AFTER OA60172, AN INSTALLATION MAY GET IEB351I I/O ERROR IF JES2IN-STREAM DATA HAVE BEEN CONCATENATED TO A 21/09/20 PTF PECHANGE

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When concatenating a RECFM=VB,LRECL=150 data set with in-stream
  data like this:
  
  //SYSUT1  DD DISP=SHR,DSN=TYY06.RECFM.VB.LRECL150(DATA1)
  //          DD *,LRECL=150,BLKSIZE=27998
  
  any inline data
  //          DD DISP=SHR,DSN=TYY06.RECFM.VB.LRECL150(DATA2)
  
  You may see RC=12 and IEB351I I/O ERROR while accessing this
  concatenated data set.
  
  ANALYSIS:
  After OA60172, JES2 honors the DCB LRECL specified for in-stream
  data sets if the record format is fixed. However, JES2 does not
  consider a 4 Byte record descriptor word (RDW) which is counted
  to the record length of variable length records, if the
  in-stream data set is concatenated with other RECFM=V data sets.
  Therefore the record length returned in RPLRLEN is not what was
  expected by the access method.
  
  KNOWN IMPACT:
  Job may fail with IO error
  
  VERIFICATION STEPS:
  1. OA60172 was applied
  2. Job with a concatenation of data sets (RECFM=V) and in-stream
     data sets having a DCB=(LRECL=nn,BLKSIZE=nn) on DD statement
  
  
  ADDITIONAL SYMPTOMS:
  WRONG LEN RECRD,IEB311I CONFLICTING DCB PARAMETERS
  
  PE INFORMATION:
  USERS AFFECTED:
  All JES2 users that have PTF UJ04470 or UJ04471 applied for APAR
  OA60172 and are having a in-stream data set in a RECFM=V data
  set concatenations.
  
  USER IMPACT:
  APAR OA60172 fixed the problem it reported but introduced a new
  problem.

  ****************************************************************
  Fixed record format instream data sets with LRECL specified
  can encounter an I/O error (RPL feedback 08022C) during GET
  processing if they are part of a concatenation where the
  first data set is variable format.
  

Problem conclusion

• TYPE/RESTART (WARM) IPL/REQUIRED (YES) CLPA (YES)
  
  CLPA is needed only if HASCxxxx modules currently reside in
  the pageable link pack area (PLPA).
  
  Code in the HASP Access Method (HAM) is updated to be more
  tolerant of a short record when padding for an LRECL
  specified on a DD statement.
